My invention relates to a device attached to a bed-frame for the purpose of adjusting the end rail so as to tighten or slacken the fabric at pleasure by means of a dovetail casting sliding in a seat so constructed as to keep the By screwing up a set-screw on each side of the bed the fabric will be tightened to any extent desired. By reversing the operation the fabric will be slackened.

Figure 1 shows the side elevation of one corner of the bed-frame complete with the device attached. Fig. 2 is asectional side elevation, showing the manner of attaching the device to the end and side rails. Fig. 3 is an end elevation, showing the dovetail slide in its seat,

and a view of the end rail with the molding '1. is a set-screw by which the dovetail slide is adjusted.

The iabric, composed of woven wire or any other material, is secured in the concavity on the end rails by a molding fastened by screws. The opposite end rail, to which the fabric is made secure, being stationary, the movable end rail can be adjusted by means of set-screw T, so as to produce any desired tension of the fabric.

'What I do claim as my invention, and desire to secure by Letters Patent. is

In combination with a bed-frame, the device consisting of a dovetail slide, D, secured to the end rail by bolt A, the dovetail slide-seat E, secured to the side rail by bolt B and screw T, all constructed as described, and for the purpose of adjusting the tension of the fabric of which the bed is constituted, whether of woven wire or other material.
